+Revisit these options:
+ CONFIG_FEATURE_INSTALLER
+ would users really need this?
+ space difference looks negligible
+ CONFIG_LOCALE_SUPPORT
+ space difference looks negligible in code
+ time difference probably negligible:
+ most changes add setlocale() or change strcmp() to strcoll()
+ CONFIG_UNICODE_*
+ CONFIG_FEATURE_SUID_CONFIG
+ might be useful for tuning security settings (like sudo)
+ CONFIG_FEATURE_SYSTEMD
+ CONFIG_FEATURE_ETC_NETWORKS
+ CONFIG_FEATURE_EDITING_VI
+ code added in libbb/lineedit.c looks non-negligible
+ required by POSIX.1 XCU
+ CONFIG_FEATURE_EDITING_SAVEHISTORY
+ Bradley Kuhn would want this enabled ;)
+ code added looks non-negligible
+ CONFIG_FEATURE_TAB_COMPLETION
+ code added is large
+ useful and popular feature
+ CONFIG_BOOTCHARTD
+ might be nice to trace boot time in an OS hackers' build of BusyBox
+ CONFIG_FEATURE_INIT_SCTTY
+ CONFIG_ASH_JOB_CONTROL
+ CONFIG_ASH_BUILTIN_*
+ CONFIG_ASH_CMDCMD
+ CONFIG_ASH_OPTIMIZE_FOR_SIZE
+ CONFIG_CTTYHACK
+ mind this in /etc/inittab
+ CONFIG_FEATURE_MOUNT_NFS
+ CONFIG_FEATURE_MOUNT_CIFS
+ CONFIG_READPROFILE
+ code is a 263-line source file
+ might be nice to do profiling in an OS hackers' build of BusyBox
+ CONFIG_FEATURE_DATE_ISOFMT
+ not in POSIX.1
+ adds no additional code
+ would be nice to have more adoption of ISO 8601
+ CONFIG_ED
+ required by POSIX.1-2008 XCU
+ interactive program, unlikely to ever be used in any shell scripts
+ old and simple editor, unlikely to ever be used by any user
+ vi will be just as easily available to use
+ CONFIG_USE_BB_PWD_GRP
+ will be using EGLIBC's NSS for file/DNS name resolution anyway
+ might as well use it for passwd/group file lookups
+ will use BusyBox's lookup functions with uClibc
+ CONFIG_FEATURE_CHECK_NAMES
+ adds a 62-line source file with one function to the build
+ will end users be adding users and groups to the system?
+General notes:
+ it might be useful to build two BusyBox packages:
+ one configured for end-users
+ one configured for OS hackers
